HENRY BAKER, OF l LANCASTER, NSYIJVANIA, ASSIGNOR TO HIMSELF AND CHRISTIAN G. HERR., OF SAME PLAGE.

Lette/rs .Patent No. 99,048, datefl/ January 25, 1870.

The. Schedule referred to in these Letters Patent and making part of the sama.

I, HENRY BAKER, of Lancaster city, in the State of Pennsylvania, have invented certain Improvements in Stove-Pipe Damper-s, of which the following is a i specification.

The'object of my invention is to form a damper that will operate like the ordinary' plain one, and which is provided with iixed side ilues,opening above and beneath an annular flange. On the one side of this flange there is a raised iiuted central disk; on the other side, a corresponding iuted ring or annular piece; so that when the flange or damper is horizontal, it closes the pipe, to check the waste of heat or draught, permit-v ting, however, the gas and products of combustion to escape through the iuted channels or openings, forming ues between the central disk and ring-piece, which open and connect with the inner edge of the annular l flange. A

rlhe drawings clearly show the construction and ar-- rangement of the parts, so as to enable any one skilled in the art to make and use the same. g

1.*igure l is a perspective view of the side to which the corrugated annular piece B is cast, or fastened by lugs b, and rivets, as shown.

(shown by Figure 5, with the ordinary screw-end and nut F.)

The annular arches or corrugations B may be cast separately with lugs b, and secured to the annular iiange A by rivets, or cast with it, as, also, the fluted disk O, the inner channels of which are marked G; and whether cast in one piece or in two, and united jointly with the ilange, they constitute circular ues, as shown by Figure a.

The short half fines, or annular portion B, admit the gas and smoke from the inside to pass out and upward through the channel C more freely than when the disk is turned down, so that the gas, &c., can only find vent by entering the openings around the flange,

and thus a great range of adjustment is obtained from l a free, open draught, by turning the damper Vertical to any angle, and, by attention, lnuch -waste of heat is prevented, and fuel saved;

I am aware that corrugated or iiuted disks and plates are used, sliding or revolving on each other, besides other devices more or less complicated, expensive, or difficult to apply. This damper is simple, and applied as is the ordinary plain sheet-iron damper, and nearly as cheap, while it affords a wide range of adjustment, and will be lfound highly desirable.

What I claim, is-

The arrangement of the annular flange A and uted disk C, in combination with the short fines or annular corrugationsB, constructedand operated in the manner shown and described, for the purpose set forth.

HENRY BAKER.
